NONSTRETCHABLE CORD.

Specification of Letters Patent.

Patented Feb. 7, 1922.

Application filed October 11, 1920. Serial No. 416,113.

To all whom it may concern:

Be it known that I, JOSEPH H. HUNTER, a citizen of the United States ofAmerica, residing at Detroit, in the county of Wayne and State ofMichigan, have invented certain new and useful Improvements inNonstretchable Cords, of which the following is a specification,reference being had therein to the accompanying drawings.

The invention relates to material used in the manufacture of flexiblehangers and for other similar purposes, which is in the form of aflexible rope or heavy cord. In the present state of the art, thismaterial is usually formed of a stranded cord of suitable dimensionshaving a covering applied thereto, and in the manufacture of hangers thecord is out into suitable lengths and provided at its ends withattachment devices secured thereto. It has been found that such materialhas a great tendency to elongate after use, due both to the stretchingof the material itself and the slipping of the engagement of theattachment means. To avoid such a result, I have devised a constructioncomprising essentially a non-stretchable central core formed of a linkchain, together with a surrounding body of flexible cushioning materialfor enlarging and retaining uniform the diameter of the cord. Thisconstruction has not only the advantage of preventing elongation of thecord itself, but also provides a means of engagement with the fasteningdevice, which will preclude any slipping.

In the drawings:

Figure 1 is a longitudinal section through a portion of the cord,showing the construction thereof and the application of a fasteningdevice thereto;

Figure 2 is an elevation of a robe hanger formed of the cord;

Figure 3 is a view similar to Figure 1 showing a modification.

A is a link chain of any suitable construction and of any desiredmaterial. This chain is covered with a body formed of spirally wo ndstgands of flexible material smite cotton. The windings are preferablyin alternate layers B and C wound in reverse directions and thedistribution of the strands is such that the irregularities in thediameter of the chain are compensated for, retaining the body of uniformdiameter. The spiral Wrappings are secured by a fabric covering E,preferably of a spiral yye ave gr, braid. The outer surface may the n becovered by any suitable ornamental material, if this is desired.

To form hangers of this material, it is cut to the proper length and theends of the sections have attached thereto fasteners F, which arepreferably provided with prongs G or equivalent means for insertingthrough the wrappings and into engagement with one or more of the chainlinks. Thus when complete, the device has all the flexibility of therope hangers, but is practically nonstretchable.

With the construction shown in Figure 3, instead of forming the bodycovering the chain of spirally wound layers, it is formed oflongitudinally extending strands H, which are secured in position by thefabric covering E.

What I claim as my invention is:

1. A non-stretchable flexible material comprising a central core formedof a metallic link chain, a bod surrounding said core formed of aplurality of spiral wrappings of stranded material alternately wound inopposite directions, said wrappings enlarging and renderingsubstantiallyuniform the diameter of the body, and a fabric cover for said Wrappings.

2. A non-stretchable flexible material for the forming of hangers,comprising a central core formed of a metallic link chain, a bodysurrounding said core formed of spiral wrappings of stranded materialenlarging and rendering uniform the diameter thereof, a fabric coveringsurrounding said Wrappings, and a fastening device at the end havingmeans for engaging one or more links of said chain to preventdisplacement.

3. A non-stretchable flexible material comprising a central core formedof a metallic link chain, a body of cushioning material surrounding saidchain and enlarging the diameter, and a covering for retaining saidbody.

In testimony whereof I ailix my signature.

JOSEPH H, HUNTER.
